I am sorry I couldn't convince you.
Orion already has this halfway there. Swipe to go forward from anywhere exists right now.
Also Arc search on ios had exactly the same swipe to navigate from anywhere feature.
I think when a carousel appears in the webpage , swiping carousel takes precedence over swipe to navigate.
Meta's Threads app has similar navigation , there is no conflict with carousel of photos and navigation. Carousel takes priority when it appears.
Even conflicting navigation is present right now in the feedback page. To type this feedback there is a new window, there are 2 scrolling planes, one for the feedback window and other for the background page and yet both scroll independently.
Why I am requesting is because it helps with reachabilty , iPhones are bigger than ever, it is impossible to use the phone one handed especially standing in a crowded bus or a metro.
Currently for Orion I have managed to solve this by rearranging the toolbar to place a back button on the lower right corner. It works for now.
Haptics can be added as an option I guess🤷♂️
Thanks
Nik
